Import, Convert, Exporting Sat, 30 Apr 16 08:58:11 -0600 Import, Convert, Exporting en-CA 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.

GH2 and FCP7 import problem Fri, 08 Apr 2016 09:59:07 -0600 klausvonperkele 14935@/talks/discussions Hi!

After 3years I finally took my GH2 back in use and shot some video. Everything worked just fine, but when I tried to import to FCP7 I had "no data".error? This happened to half of my material? Others imported just fine. Any ideas what has gone wrong? GH2 is hacked with (maybe Flowmotion hack? no quite sure…) i tried google for answers, but none of them worked for me… Anyone got some ideas what should I do?

Using alpha channel for correcting playing video? Mon, 19 Oct 2015 00:54:08 -0600 Vesku 13955@/talks/discussions Is there any way to use real time image adjustments with alpha mask channel in video player?

I have uneven back light in my TV and it would be nice to have a masked correction for display faults. Corner color and contrast are also fading when watching very close. A mask correction would help for that too.

Do you use banding filter? Fri, 25 Mar 2016 03:38:21 -0600 Vesku 14868@/talks/discussions I have found a way to improve my playing GH4 videos using clever dithering by banding filter. It removes noise, banding and rough colors and the result is like 10bit video in 8bit screen. I use Potplayer but I think there is bedanding filter in other players too. I have one sample frame. Look the smooth gradients and still very sharp details. The effect is even better in playing video. The trick is to use that filter in player so that the re-compression is not removing dithering effect.

collecting ideas to build up a AVCHD - ProRes - Resolve workflow. Fri, 21 Sep 2012 17:59:55 -0600 peaceonearth 4670@/talks/discussions I had two large project of 3 days shooting each (for me it's large), having shot some hundred clips in CM Intra patch means 300 - 400GB of data for each project. I had no story board as basis for a timeline just rough ideas of my clients so I had to review all the clips and started to work natively in PremierePro to create a story line. I am quite happy with Premiere and native mts files but there was some grading neccessary and I had to hand over the project to a colorist. It doesnt work with mts files.

I could have converted all files to QT ProRes before starting editing but it's needless to mention that the huge amount of data is hard to deal with and converting is time consuming too. How could I do it better next time?

What do you think? Would be a total mess or will work for them? Thanks

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.

XAVC-S vs MP4 Recording Formats Sat, 05 Mar 2016 04:53:12 -0700 glenpinn 14713@/talks/discussions Hi everyone, i am in the market for a new 4k Video Camcorder, after dumping my FZ1000 last year as it just didn't suit my Run-n-Gun shooting style when mounted on my hand rig and my Flycam HD3000 stabilizer.

I have kind of short listed between the new Sony AX53 (1/2.5" sensor) and the AX100 (1" sensor) as it seems both Cams offer me everything i need for the type of shooting style.

That aside, both record 4k/25p and 1080/50p in the XAVC-S format @ 100Mbps, and my previous FZ1000 Bridge Camera recorded in MP4 @ 100Mbps, but back when i got the FZ1000 i had not really heard a lot about XAVC-S as i rushed into getting the FZ1000 because it was cheap.

so my question is, i have read some stuff about XAVC-S being a more efficient format than MP4, others just say that is not true, and i just can't seem to find anything definitive about how they both work, and if one is actually better than the other, for both 4k and 1080 modes.

My friend has a Panasonic VX870, and it shoot 4k/25p MP4 @ 72Mbps (it only averages 62 to 65 max so far) and the 4k seems to look ok, but i have seen some samples from an AX55 (ak AX53) and it just seems to look nicer for some reason XAVC-S at a higher bitrate maybe, better glass, better sensor, not sure)

If anyone can shed some light on XAVC-S vs MP4 i would appreciate some advice, or links to some useful information.

Sony Vegas Pro: Transcoding, importing and exporting Fri, 08 Jun 2012 02:01:03 -0600 DeShonDixon 3504@/talks/discussions Does anyone know a good codec for format to convert my GH2 footage to before it enters Vegas without losing any quality at all? Because importing the GH2 footage nativity lags like crazy on my not so fast PC. And also I've tried 5DtoRgb or whatever its called and when enter I import a shot into it, it just crash on me so that won't work for me and neither will converting my footage to AvidDnxHD codec cause that lags like crazy in Vegas too. I've converted my footage to 35mb XDCAM in vegas which works great but I lose quailty. Also I need help with my exporting to the web. I normally edit my footage nativity while its lagging like crazy then export out as Cineform.avi with 4:2:2 selected and Filmscan 1 then I convert it to H264 using mpegstreamclip but I lose a buttload of quailty. I've also tried virtualdub and converted to .avi x264 but doesnt work so well for me either neither does converting through Adobe's Media Encoder. I've also tried to export directly out of vegas as a .mp4 but even at two pass vbr 70-240mb. Like I know im supposed to lose some quality when uploading to the web but I tend to lose a whole lot! I see people that export at only like 10mbs and get much sharper footage than me! Also is there anyway to import a vegas project into after effects? I know FC7 or Avid can do it with automatic duck. Does vegas have anything like this or anyway to do this? But yeah I know im asking a lot but if anyone could help that would be great!

workflow with gh4 footage and LUTs Wed, 21 Oct 2015 04:09:31 -0600 paglez 13972@/talks/discussions Hello. I'm absolutely newbie using LUTs with my GH4 footage, and I have a plenty of doubts:

Once I have my raw footage into NLE (Adobe Premiere) whats it's the sequence order to apply the LUT?. I do the following procedure:

A) I put the footage in timeline. B) I apply a Filmconvert profile ( GH4 and Vlog) or Lumetri input tecnical LUT C) Then I open 'color' tab; I go to 'basic' tab and I do the necessary basic corrections, but I doesn't apply any input LUT. D) Finally, in Advanced tab, I make my 'creative' look and I apply a Output LUT.

It is correct this procedure? Thanks.

PHOTOfunSTUDIO 9.7 PE Sun, 18 Oct 2015 13:06:20 -0600 Scot 13952@/talks/discussions My question or observation in need of confirmation is on the format conversion function. I need to convert my G7 4K footage to either FHD MP4 or MOV but I'm having an issue. The first is that my 24 fps footage is being converted to 30 fps and I see no way to stop that. Is this the way it is or a bug anyone else notice it? The other issue is I converted to both MP4 and MOV and the MOV file seems to be identical to the UHD file visually but the MP4 version definitely has increased contrast. Can anyone explain this? Looking for any solution or suggestions. I'm using Resolve 12 to edit which on my system has a very difficult time with the UHD files which is why I need to convert.

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..?

Slowing down a filmed screen from 50p to 25p Wed, 14 Oct 2015 09:49:50 -0600 TimTomTum 13930@/talks/discussions Hey guys,

for a video installation I need to film a screen and stuff happening around it. When I import the 50p file to premiere and slow it down to 50% the footage looks choppy. Why?

So the process: I have 50p footage on the screen. Check. I film it with 50p check. I slow it down in premiere: Fail.

Anybody knows what that could be?

Cheers, Tim

QUESTION - GH2 AVCHD Timecode Corruption on Import into FCPX Sat, 01 Dec 2012 19:34:22 -0700 nyexcuse 5349@/talks/discussions So I have had this issue for a couple weeks now, and I don't know where else to turn.

I hacked my GH2 a few months ago and things have been pretty lovely so far. A couple weeks ago, however, as I was importing some AVCHD files from my SD card (64GB SanDisk Extreme) into Final Cut Pro X and some of them gave me this error upon import:

"Import Failed: The following clip encountered an error during import and is still referencing media on the camera: Clip Name: 2012-12-01 19:21:00 Event: X Original Name: Clip #X Volume: NO NAME"

After looking around, I noticed that the files that presented this issue had a strange timecode. Instead of displaying a normal start time of "00:00:00:00" they started with "23:27:41:06". Only some files are like this, and as far as I can tell it only happens to clips that used lenses that have been adapted to the camera (non-4/3 Panasonic lenses).. Other than that I don't know what's going on.

Has anyone else had this issue? Is there anything I can do to fix it?


What is the right ratio for anamorphic 4k gh4 footage? Wed, 30 Sep 2015 13:07:30 -0600 tigerbengal2009 13860@/talks/discussions Hi sorry for this basic question but I am really confused about aspect ratios with the gh4, a friend of mine shot a video with his gh4 using an anamorphic attachment 1.75x, he was using 4k 3328x2496 in 4:3 anamorphic mode. with a regular camera that shot 16:9 I just multiply the width for the anamorphic number either 2x, 1.5 etc and the video looks fine, but gh4 4:3 mode I do not understand how to find the right ratio.

how to unsqueeze this on Premiere of FCPX?, I tried 1.78x 3328 but this is not the answer because of the 4:3, what is the logic/numbers to convert anamorphic 4:3 to proper ratio 2.39:1?

also he shot some pictures, I attached an example, which is the ratio to convert the picture to the correct size?

any help suggestions would be appreciated, thanks in advance

Looking for high dynamic range content for HDR experiments Sat, 19 Sep 2015 09:37:51 -0600 karl 13746@/talks/discussions Hi, I am looking for some sample video material which I could use to experiment with generating HDR videos compatible with contemporary TVs.

At one can find only two commercial samples, that's all I could find anywhere.

I have been able to generate videos which my 4k OLED TV recognizes as "HDR" by using:

x265 --preset ultrafast --output-depth 10 --transfer smpte-st-2084 \ --master-display 'G(13200,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)' \ --max-cll '10000,400' input.y4m output.hevc

ffmpeg -i output.hevc -c copy final.mp4

When replaying "final.mp4", the TV switches into HDR mode, and the content is displayed with what appears to be very high contrast.

I haven't experimented much with the master-display and max-cll settings yet, but this wouldn't make much sense with the input videos that I currently have at hand, which simply are of "low dynamic range", and are only of 8bit per channel accuracy.

If you have some sample video material with a very high dynamic range (like shots of scenery with surfaces emitting 400 or more cd/m^2, like a mixed shot of dimly lit indoor stuff in one place and some brightly sunlit plants visible through a window outside), you could make me happy by making it available (in a format conveying at least 10 bits per color channel).

Actually, anyone with a Magic Lantern patched full frame camera (or an Arri Amira) at hand should easily be able to create such a sample shot.

Youtube videos re slightly out of sync. Why? Wed, 26 Aug 2015 12:03:59 -0600 dlzn 13614@/talks/discussions I've noticed my videos are now slightly not-synchronized, after they have been uploaded for months, for an unknown reason. I mostly view them in Google Chrome. But I don't think it's browser related.

I shoot with a hacked Panasonic GH2, mostly Flowmotion V2. My upload codecs are usually h264 .mp4 varying from 24fps to 50fps. Nothing too extreme. When rendered and exported everything is pretty much synced. But on Youtube they are off.

I work on a Macbook Pro Retina (late 2014) 2.2 Ghz Intel Core i7, 16GB RAM

Does anyone know why or how to fix this? Or is it just me and am I going crazy.

Using Proxy for my GH4 4K .mov files with PPro CC 2015 Sat, 25 Jul 2015 11:00:59 -0600 soulkeeper 13454@/talks/discussions I'd like to avoid upgrading my pc right now so i'm trying to find alternatives (proxy files-settings in ppro etc) in order to be able to edit my files.... I've got 8gb memory (maximum supported from the motherboard) and i've set 5,5gb(2,5gb for OS) in ppro from the settings menu... Imported files (120gb of 4K .mov gh4 ) i'm getting a low memory message (after 5-10minutes) and i have to quit the app.

Will transcoding to Prores 442 4K proxy (3840*2160 res) help with memory problem? It sure helped with cpu load (90% vs 35%) for a 4k file in a 1080p timeline...the proxy 4k file is double the size of the original (converted with cliptoolz) but before i do the same for all the project i'd like to know if i'll solve the low memory message?

Any other suggestions for dealing with low memory message?


Windows says DNG is 48 bit (3*16) when it is actually 24bit(3*8) ? Mon, 06 Jul 2015 05:59:20 -0600 mala 13327@/talks/discussions Title says it all really, I have some RAW images from a machine vision camera which have been run through a custom bit of software to save them as DNG. In Raw Therapee, Raw PhotoProcessor and photoshop on OSX they are correctly "tagged" as 8 bit, yet on windows with Adobe DNG codec installed, windows picture viewer says they are 48 bit ?? Has anyone experienced anything similar ? or have any idea why this might be ? We also have a colour matrix problem that may or may not be related, with high green tint, though if "no profile" is selected in Raw Therapee the image is displayed correctly and RAW PhotoProcessor always by default opens and exports the image correctly.

Thanks for advance for any suggestions. mala

Encoding Helper - Public Alpha - Feedback wanted Sat, 30 May 2015 05:30:56 -0600 jondezwaan 13079@/talks/discussions Hi guys!

Longtime lurker here.

As part of my graduation project, I'm trying to develop a (web)tool which should make video encoding a lot easier and faster. It's actually a follow up to my previous research, in which a lot of (pro) participants stated that time is often a limit to quality. This tool should provide the best settings based on time and hardware, but it's possible to get settings without those parameters as well. After learning some basic PHP skills, I've completed the base code and I think I need to share it first, before I continue to develop the tool any further. Let me know what you think and most importantly: don't be gentle!

You can view the tool here: link and if you've got any spare time, please provide some feedback in this topic or at the form below the website.

I know there are some issues regarding 4K encoding advice (didn't properly implemented a VP9 algorithm yet), but please any feedback is welcome!



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:

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



GH1 fcpx Sharing video problem Sun, 24 May 2015 07:16:33 -0600 shabram_2222 13041@/talks/discussions I have a GH1 hacked with lpowell peak reliability setting and I'm having trouble getting my videos out of fcpx without this strange interlacing problem. I'm not sure if its interlacing or not. The steps I take are-go to share, select master file(default), Then I've tried both h.264 and prores 422 which is what it said the source was. Another peculiar thing is that the frame rate reads 29.97 but I thought the hack I have gives native 24fps. Maybe it's a frame rate problem? I've attached a screenshot of a video freeze frame. H.264 made it a little better but it's still really bad. Whats going on here?
