Import, Convert, Exporting Sat, 18 Apr 15 07:09:39 -0600 Import, Convert, Exporting en-CA Windmotion - upsampling to 4:4:4 Fri, 25 Jan 2013 20:57:48 -0700 zsero 5909@/talks/discussions I've just seen this post over at doom9 forums about a guy making a super high quality filter to upsample to 4:4:4 16-bit. Especially for GH2 / GH3 owners. Trying to invite him over here.

Free program for .mts to virtually any (editing)codec conversion (XMedia Recode for PC) Thu, 25 Dec 2014 09:46:56 -0700 MrZz 12030@/talks/discussions Hey guys just wanted to share an easy workflow I found for converting my raw .mts-footage to .mov-files with DNxHD 120 (very good editing codec from AVID - even my Netbook is capable of offline editing with this, for better quality use DNxHD 180 or else). This program: can do batch conversion of video (and also audiofiles). It has a lot of settings for each different format it can convert to (I use MOV and then the VC3/DNxHD set. you can then decide which setting of the codec you want to use, e.g 1080 at 25p with a bitrate of 120 Mb/s -> DNxHD 120, which I highly recommend but you can convert to virtually any video format) If you don't already have it installed, download the AVID Codec pack:

Smart Rendering GH4 4K on Windows? Wed, 28 Jan 2015 06:05:46 -0700 NickHope 12262@/talks/discussions Before I start archiving the best parts of my footage in MagicYUV lossless .avi format at a bitrate 18x bigger than the original, I am wondering if anyone has found a way to reliably smart render (no recompression) 4K UHD MP4 footage from the Panasonic GH4. My typical nature footage features a lot of unwanted head and tail. Really I just want to split the files on the PC, not in-camera. I don't care if it's forced to i-Frames or if the first and final GOPs don't render well.

The "main" NLEs won't do it. I tried TMPGEnc Smart Renderer and that didn't work. I expect it's beyond VideoReDo and Womble.

I have heard that Cyberlink PowerDirector tries it but there are glitches in the result from version 12 (reported at ). Unfortunately the version 13 trial version doesn't support 4k so it would mean spending $80 on the program to test it.

I also notice that Corel VideoStudio Pro X7 features "4k smart rendering" and there is a fully-functional trial version but it's 800MB.

Diagonal rain appears using GH2 + Premiere Pro CS6 without a hack Mon, 11 Feb 2013 19:53:46 -0700 PeterParkorr 6094@/talks/discussions Hi,

I've been trying to work out why exporting some noisy low light footage in premiere pro CS6 is giving me 'diagonal rain' problems that aren't present in the original m2ts files from my GH2.

Reading two similar topics (below) the problem seems to be related to GOP length, which hack is being used, and the decoding abilities of certain players. But I shot this footage with the original firmware so this can't apply? Possibly it is a CS6 specific issue?

It's not footage I can take again so any advice on how to export this without the noise would be amazing... I'm a beginner but not posted it there as the problem seems to be a complicated one.

I just uploaded the start of my edit to youtube for an example of the problem. Some of my footage was 24p and some was 50 fps 720p but the problem persists in all the export formats I've tried;

Need Davinci Resolve Lite 9.0.4 Mac .dmg Wed, 27 Aug 2014 02:19:03 -0600 Psyco 11135@/talks/discussions I'm need Davinci Resolve Lite 9.0.4 as its the last version that runs stable on OSX 10.6.8. I want to convert the raw files from BMPCC and can't upgrade the OS because of other hard- and software (and because I want an OS I can work with;-).

Has anybody still that .dmg or .zip and can upload it for me to some file sharing platform please?


4K Downscaling progress topic Thu, 19 Jun 2014 17:13:01 -0600 RRRR 10637@/talks/discussions I couldn't find anything dedicated (and I may have missed something important) so: This is a topic dedicated solely for any kind of progress updates on software, code and methods to downscale 4k with best possible results to help people establish a workflow for converting 4k footage. Meanwhile, it may be a good idea to also map the best downscaling methods that already exist.

Frame Rate Downscaling / Frame Averaging Fri, 16 Jan 2015 04:47:25 -0700 Athiril 12188@/talks/discussions Anyway, the basic idea is the same as image stacking, you stack 2 or more images, one of the advantages is if you do it in a high bit depth space, the bit depth of the image will go up, that means 8-bit images increase in bit depth when the stack is calculated in a higher bit depth space.

I commented off hand that if you're desperate enough you can get higher bit depth from merging frames together if you have access to 50, 60p etc. Oh, this also works if you downscale a higher resolution to a lower one within a higher bit depth space as well - so for all you people down scaling footage, if you're able to do that in a 16-bit space and save a high bit depth format then you'll have something to gain. I didn't speak for practicality, only that it can be done.

When I wrote my program to count unique colours in very large resolution 16-bit tiff images, I didn't see other software that'd do that. As the array would require tremendous memory. If you want to know the way I managed to do it I had a simpler way to do it which required processing power over memory, and that was to sort the pixels in an array from smallest colour value to highest essentially, that way you could simply not add +1 to the unique colour count if the same colour appeared more than once in a row.

I had other reasons for doing this, it's part of my experiments with image stacking, but I've done it with various image sources, scans, jpegs from shitty cameras with no raw, raw, jpegs from better cameras, snap shots of two frames in video.

Been told it's "cant be done" many times. Because the information from one from to the next isn't the same - well no, that's exactly why it works, even in the worst case scenario of a tripod locked off shot of still life with nothing moving it works.

But if you're recording 50p, blending every 2 frames together just speeds the footage up to 25p, the average of the two frames still contains the same amount of motion blur/movement as recording in 25p at the same shutter angle, though it may be divided into 2 sections over the 1 frame instead of 1 long section of motion.

Generally that shouldn't be an issue as 180 degree is accepted as general purpose good shutter angle which leaves space between the movement/motion blur anyway, and if you wanted none you could shoot 360 degree.

Now to the screenshot - R, G, B bit values, these represent how much of the scale Red will use on it's own (regardless of what green and blue is attached to - the same goes for Green and Blue etc), a value of 6-bits would mean, the image only has 64 differing red values in total. I made this to identify problems with some images.

Unique Colours is the total number of colours, an 8-bit image has a maximum value of 24-bits here, but that would be very hard to achieve, as it would have to have every combination of colour, hue, intensity, saturation in the one image etc from bland to neon, and the image resolution would need to be 16.7 million pixels or over.

The Unique Colour Factor - A 1920x1080p image has 2,073,600 pixels in the frame, a value of 50% would mean it would have 1,036,800 unique colours in the image, this percentage can be used as a factor of colour quality and separation.

The first example is a single frame grab from some A7s (720p 120fps) video I downloaded off the net (I was going to use my GH2, but I left it at work this afternoon), it's placed into Photoshop and converted to 16-bit and saved as a tiff (partly to rule out any conversion to 16-bit as the contributing rise in bit depth counting, and also because the program I wrote only reads 16-bit tiffs at this time of writing).

The second example, is the first 2 frames in 16-bit mode in photoshop, blended with opacity at 50% for the top layer, flattened and saved as a tif.

The fourth is the same but with 4 frames.

As you can see, the more you stack, the more in between values with higher precision than 8-bit arise, about ~9x the unique colours.

It should only be logical, even if the video or two photos is of on a tripod of a still life, 2 pixel values will have variance in them over the two frames, especially since 8-bit has high quantisation error compared to higher bit depths, variable noise, micron image movement etc, so if you have one that's 241 and 240 for example, the in between value cannot be represented in 8-bits.

Unfortunately I'm working tomorrow, but that means I can get my camera back before Monday, so I probably can shoot some footage with the lowest contrast settings and see if I can induce banding in something and post up an actual video sample.

5DtoRGB for GH2 - advantages vs disadvantages? Thu, 28 Jul 2011 18:27:48 -0600 qwerty123 530@/talks/discussions What Bitrate level of DNxHD conversion? Wed, 23 Apr 2014 22:13:29 -0600 dancerchris 10238@/talks/discussions I am tired of all the editor problems dealing directly with our beloved GH2 .mts files. I want to convert to intermediate like DNxHD and would like to know what Bitrate should be adequate for capturing all the detail that a good Hack (in my case Moon T5) has. Any suggestions. Is it the same amount of the max bitrate in the clip? The DNxHD files are quite a bit larger, so minimizing this value will help to save space.



Playback of edited 4K on camera Sat, 20 Dec 2014 16:37:15 -0700 SAS 11999@/talks/discussions Hi all, I have searched for existing answers to this question/issue all over this site and google, but have yet to find anyone with the answer:

I have the FZ1000 but I hear the problem is the same for GH4:

I can currently only playback individual 4k clips in camera over HDMI to a 4k TV, but I wish to make an edit and play it back...

Is it possible, once I have edited a 4k Video, to make it playable in camera so that the edit can be displayed over HDMI on a 4K TV or monitor?

Many Thanks for any solutions, as my friend has a 4K TV and I have a FZ100 so we would like to be able to playback an edit in camera over HDMI so that we can watch my work..?

Compression not supported and other weird problems with .MTS files Sun, 16 Nov 2014 08:37:00 -0700 MetaControl 11773@/talks/discussions I am working on a project of mine, which was shot with a hacked GH2 and a hacked 5dmkii. I did much of the editing a while back, but then i had to change computer; including a transition from windows 7 to windows 8.1; i started editing the project in PP & AE CC back on my old machine and all was fine. but recently - it seems like it happened with the big 2014 update (as i am obviously not the only one who has issues) - i am having trouble with my .MTS files from the GH2. I use them outside the stream folder structure as individual files. and i had the weird bug, where i had to rename folders to make my files work in Premiere after the update (as they suggest as a workaround in the official forums). But now, i am having problems with the MTS files outside of premiere too. I wanted to make proxy files out of some of them, or check them out with gspot. something is wrong with the compression format, the codec or something. i tried re-installing quicktime (i think to recall that the mts is a mpeg2 wrapper) with no luck. does anybody have an idea what it might be?

WinRewrap - Batch ReWrap MTS to MP4/MOV . Sun, 30 Sep 2012 17:42:50 -0600 fatpig 4775@/talks/discussions Hello,

I wrote a little Tool called WinRewrap. It will Batch Process MTS Files to MP4/MOV and adjust References to the MTS accordingly in your XML File. It uses ffmbc. ( ) I wrote it primarily for exchange between the new Sony Vegas Pro 12 and DaVinci Resolve. But it can be used for any Batch rewrapping task of MTS.

Of course, this is a very early version, so please let me know any problems that may occur. Note: Audio was converted to AAC in v0.1. Later version keeps the audio stream.

I hope you can use it as well as I can. Ideas, suggestions and Bug Reports, please post here.




The Homepage is still in development. Anybody who would like to donate a small amount is appreciated :)

WinRewrap v 0.4

Changelog 0.4:

  • Added Cancel Option while ReWrapping
  • Added PCM and No Audio option

Changelog 0.3:

  • Added Option to Convert Audio to AAC
  • Added Check for 0-byte Files (returns error now)



  • ffmbc.exe (Release was tested with version 0.7.1 rc7) put it in the same folder as the WinRewrap exe.

  • Windows 7 / Vista Users may experience errors related to writing permissions.

Fix: Turn up your UAC to "always notify". if you turn it to not notifying, some applications are automatically denied access. like winrewrap.

to fix those, copy WinRewrap and ffmbc.exe to your Project Folder. (Tip: WinRewrap starts with its containing Folder under the Browse Dialog, If its your project Folder you can just click OK.)



support for rewrapping .MTS Files to .MP4 and .MOV using ffmbc.exe

this is essentially a frontend for ffmbc, designed for batch processing project folders containing multiple MTS Files and optionally an XML.

This enables project export from The New Sony Vegas Pro 12 to DaVinci Resolve, and can also be used for normal batch processing of entire Folders from GH2, etc.

It will automatically replace the MTS extensions to your new Container inside the XML, so you can automatically use it with the rewrapped files.

Known Issues:

Big Endian PCM Audio is not supported in Stream Copy Mode as of Version 0.4 (AF100) WinRewrap can, however convert to little Endian PCM Audio.

Bug reports please in the dedicated thread on



5DtoRGB - not sure if someone know's what issue I've got Mon, 15 Sep 2014 14:27:15 -0600 JayUKB 11291@/talks/discussions I've tried to use a 1.5.4 version of 5DtoRGB (yes, XP!!) but it keeps crashing after loading the file and pressing convert.

I'm on Windows XP, so looking to convert to DNxHD (codecs already installed). Also, to make matters worse, I'm using a laptop.

Would anyone who has used/uses 5DtoRGB have any idea?

Strange jitter effect from GH2 footage in 720x480 render Sat, 21 Jun 2014 16:28:44 -0600 Brian_Siano 10649@/talks/discussions I'm finishing up a big project, which I shot with about seven different cameras; Canons, a Panasonic camcorder, a GH3 and a GH2 using the Cake patch. The original footage is 1080p. I rendered the streams down to 720p for easier editing. I used these to render a 720x480 final product for a DVD. I'm using Premiere pro CS5 for all of this.

The problem is that the footage shot with the GH2 jitters oddly, like an old silent movie filmed at some archaic framerate. It's not catastrophic, but it's noticeable to me. I don't know why this is. Every bit of original footage is 29.97 fps. The scaled down versions I edited are all 29.97 fps.

I can think of only two things. The GH2 was using the Cake patch, which may have been a reason. Or, the GH2 was one of two cameras storing its video as AVHCD, while all the rest used MOV. But the other AVHCD footage looks fine.


ADENDUM. Watching the original footage reveals that it appears to be interlaced. Don't recall shooting it in 1080i, but I guess that's what happened.

Automated Avid, ProRes & LW format conversions - auto file renaming tools Sun, 04 Mar 2012 22:48:16 -0700 notrons 2486@/talks/discussions I'm looking for people who are interested in automated .mts file conversions to ProRes and Avid DNxHD 4:2:2 formats, or for import into Lightworks, to test my new DSLR Post Prep Utility Windows application. The program is designed to automate the process of creating either and or both HQ and proxy conversions on demand, automatically by watched folder, or can be scheduled for off-hours. It uses the ffmpeg engine for all of the conversions (which run in their own minimized windows). When in watched directory mode it can also be minimized to the system tray where it continues to provide notifications and watch for new files. The following conversions are currently supported;

HQ Formats - 4:2:2

Uncompressed 4:2:2 10bit (working with LW)
ProRes 4:2:2 YUV 10bit 176Mbs HQ
DNxHD 4:2:2 YUV 10bit 176Mbs HQ
MPEG4 Wrapper for Lightworks
MPEG-2 4:2:2 I-Frame w/ M701 tag (for Lightworks only)
MPEG-2 4:2:2 I-Frame (w/out M701 tag) 

Proxy formats

ProRes 4:2:2 YUV 10bit 36Mbs
DNxHD 4:2:2 YUV 10bit 36Mbs 1080P 24
DNxHD 4:2:2 YUV 10bit 60Mbs 720P 24
DNxHD 4:2:2 YUV 10bit 145Mbs 720P 60
DNxHD 4:2:2 YUV 10bit 115Mbs 720P 50

DNxHD and ProRes HQ conversions seem nearly identical, but I think ProRes is a little better quality as a proxy format. DNxHD renders much faster than ProRes. I have a beefy workstation with Matrox hardware and it can handle all of the usable formats pretty easily but I would love to hear about how they work out for others. Please give it a try and let me know about the experience!

Check out for more info. Also available are tools that add custom prefixes and timestamps to files on a directory-wide basis - to help keep clips uniquely named and organized (ExtensionCord). You might want to grab the Matrox and Avid codecs while you're there and download a copy of HD-MINI to audition clips on demand.

With this utility you can select a different flavor of HQ codec from proxy codec and have both conversions done automatically and off-hours. If you use ExtensionCord to add a prefix and (file creation) timestamp to your files before converting, you can edit with the proxies and then offline / link to the HQ clips of exactly the same name at render time.

I hope you can find some use for these ...; )


Anamorphic rendering in Sony Vegas Pro 11 Sun, 15 Jun 2014 04:26:32 -0600 raf702 10607@/talks/discussions Hey all, I shoot on a Panasonic GH2 with an Iscorama anamorph 2x lens. I seem to have an issue with rendering to a stretched format for anamorphic viewing. 

For project properties I can set it to 3840x1080, but in the render options under custom templates. It won't allow me to use a custom 3840x1080 under the custom project size, for rendering under QuickTime which is the codec I always use. It changes to a random project size of 2048x1152 when I enter the values I want. I have no issues when using a squeezed format, but I'm trying to do a stretched format.

I appreciate anyones help and tips! Thanks

GH4 & Render settings Thu, 03 Jul 2014 02:25:23 -0600 PatrickDSLR 10717@/talks/discussions Hi there,

I've just got registered on this forum, after only reading (and learning!) for a while. Thanks for that! I've recently bought the Panasonic GH4 and now I'm about to finish my first videoproduction with it.

I've attached my project properties and render settings, but i'm wondering: what are the best render settings for the best image quality? And what are the best settings for Vimeo/YouTube purposes? In terms of bitrate, etc.

I will capture my footage @ 4K, but I will render it as a .mp4 full HD file.

Hope to hear from you!

Premiere Pro and DVD authoring question Mon, 02 Jun 2014 18:40:31 -0600 Brian_Siano 10522@/talks/discussions I'm working on a project where roughly seven video HD streams (both 720pand 1020p) are going to be rendered down onto a DVD (720x480). Thing is, when I do test renders from Premiere Pro (CS5) to check the quality, it takes a phenomenally long time. For example, a four-minute excerpt takes about two to three hours. The final product is roughly 2 hours long, so I'm looking at a looong render time.

I'd like to know any strategies for shortening this process. Would it be best to simply import the sequence into Encore,. and let Encore handle the DVD rendering? Or, should I use Premier Pro to export the video to an MPEG-2 file, and important that as an Encore asset?

(Also, if anyone has an FAQ on how to adjust render quality in Encore, send me the link. I've never been able to figure out anything beyond the basic bitrate setting.)

Importing with Premiere Pro CC Tue, 27 May 2014 18:42:55 -0600 thejohnroman 10470@/talks/discussions My work just switched from Final cut 7 to Premiere CC ! I use Premiere at home and for side projects, but I ran into a problem. I shoot with a sony EX1 at work and would use XDCam transfer to bring it into Final Cut, it would place it in the correct scratch disk and I could go on my way editing. Time is an issue i usually have 15 mins to shoot and edit before it airs. Now in premiere I don't believe i can do this, but hopefully I am wrong. So does any one know how to Import footage straight from a card into premiere sending the footage to where i set my scratch? Thank you!

XAVC-S ( free ) conversion ? Fri, 16 May 2014 13:52:25 -0600 kurth 10394@/talks/discussions Interestingly, in preparation for getting an xavc-s camera like the rx100mklll sometime in the future, I've done some tests looking for a ( free ) conversion software for xavc-s to mov. It looks like gopro cineform does the job, although it's only a windows application. I tried some native mac apps like compressor, mpegstreamclip, and toast. None worked. I highly await sample clips in xavc-s from the mklll. The sample I did my test was from the sony as100v. Anyone have any other free solutions ?

Best Export Settings when Shooting SD?...yes SD! Tue, 29 Apr 2014 22:50:49 -0600 matt_gh2 10280@/talks/discussions I've been asked to edit some footage that was shot in SD. Editing in Premiere Pro CC. I know my optimal export settings when editing 1080P HD, in terms of using VBR 2 pass and setting optimal Target and Maximum Bitrate. Does anyone know if there are optimal export settings (for H.264 for YouTube and Vimeo) for footage shot in SD? Didn't know if they differ from what works with exporting HD footage. Thanks
