Davinci Resolve - add one frame at end of each clip?

oscillian — Thu, 09 Aug 2018 04:00:24 +0000

Bit of a noob thing here: I imported 50p footage to a 24p timeline and finished the project. Resolve can't change the timeline after the first clip is conformed, so... I selected all the footage, deleted everything, changed the timeline to 25p and CTRL+Z:ed to bring back the footage.

All good, but... all clips are one frame short, so the resulting movie is too short. How can I add one frame more at the end of each clip?

Any ideas are truly welcome :-)

GH2 - GF2 drewnet v6 PAL - NTSC output influence on 24p footage

eventive — Fri, 11 Jul 2014 14:38:02 +0000

I've been using my GH2 with the drewnet v6 hack in NTSC output mode for a long time (in PAL land). Now that I've got an extra GF2 (also drewnet v6 installed), I want to combine footage of both the camera's. I'm thinking about using 720 25p on both camera's to do so (unless someone has a better idea). But I'm also in the middle of a bigger 1080 24p project on the GH2. When I change the GH2 from NTSC output to PAL, does this influence the 1080 24p footage in any way?

LX7 or GF6 + 14mm for video?

stereotype — Tue, 29 Apr 2014 00:31:00 +0000

Planning to get either an LX7 or a GF6 to use as a compact to always have with me, 25p video being my main use. Already own a GH3, looking for something lighter and cheaper so I can take anywhere without much worry, throw in the back seat of the car, film the kids at the beach, etc...

The two cameras are similar in size, and also more or less in price (after selling the GF6 kit lens). Also intend to be using an ND filter with either to help get the correct exposure for aimed frame rates. If getting the GF6, I'd be using the 14mm + ND both of which I already own (until I get hold of a Sigma 30mm DN to replace the 14mm, same filter size).

At 1080/25p, both seem to cap the video at 20Mbps, but not sure if the compression efficiency is similar?

Does anyone have any practical experience with these, mainly with regards to video quality?

Do they both have adjustable color modes for video like the GH3? Vivid, natural, etc? Can you tone saturation down, etc?

How nice is the LX7 lens? And how does one attach a filter to it? Do you just unscrew the lens cover, and that's it? Or do you need some sort of adapter? I've googled and youtubed, but still a bit confused about how to use those 37mm filters on the LX7...

I've compiled the following "pluses" for each of them:

LX7: Internal ND filter, slightly more pocketable, fast lens, slow-mo@100pfs.
GF6: Adjustable LCD, bigger sensor, changeable lens.

Any inputs? Which one you'd rather get?

Thanks!

AVCHD VS MJPEG

Manoosh — Thu, 22 Aug 2013 12:45:42 +0000

Hi everybody.

Thanks to every workers and tester for your job.

I see lot of post about Mjpeg vs avchd, the majority of people say avchd better than Mjpeg. But today I'm not sure...

I was making a shot test between 24h/HBR/Mjpeg with "Driftwood Cluster X series 3:│moon T7" The scene is very contrasted with highlights and black.

I prefer Mjpeg...!!! Because the noise is the same and I see more details and more sharpen.

I want know if somebody testing Mjpeg and say the same thing.

25p and 2K possible? with the option Mpjeg fps of ptools?

The time limite?

Mjpeg in 2K 25p no limited time, It 's dream for me.

Thanks for your answers!

GH2 - 25P and 1080P?

lmackreath — Thu, 14 Feb 2013 03:37:47 +0000

Morning all!

I currently have a UK PAL Sony Nex 5N and am happily using it to shoot away at its optimum settings at 25p 1080p. I now have purchased a GH2 in the UK and am aware that I can hack the GH2 and get 25p as well as 24p but with the 25P HBR Option on all hacks I can only see a 1080i option and not a 25p 1080p option?

Could someone please explain to me why this is?..and maybe more importantly does this matter?..will I still get great results using the interlaced 1080i and/or is therr a reason why the GH2 and any of its hacks dont offer 25p 1080p?

I have searched this forum and googled the answer and have seen topics about this but no real definiative answer, if anyone could advise it would be appreciated. Ideally I just want to be able to shoot at 25p in the UK but still be able to get the best resoultion settings which I have always believed to be 1080p?

thanks in advance

the most updated Stable Patch with span for 25P PAL

kenjikarma — Fri, 23 Nov 2012 04:13:47 +0000

HI guys,

I got a japanese version of GH2 but I'm in hongkong. So I'll be shooting with PAL 25p. I've read the previous threads about the stable patch for 25p dated 16mar. Mostly Gop3zilla + sedna A settings. However, when i loaded the hack, there is still no language menu for me to choose from unlike other hacks. Also, I'm wondering if there is any update on the stable patches that works great for 25p? Thank you so much.

25p for NTSC gh2 (from USA)

tomek123 — Wed, 17 Oct 2012 15:57:23 +0000

Hi,

I have a brand new GH2 (couldn't wait for GH3) form B&H for cheap.

I installed Apocalipse Now patch and I can't find a way to shoot in the best quality at 1080 25p (progressive). Looks like there's some option for 1080 25i, but not in HBR mode (as I understand this is the best quality mode) . In HBR it can make only 30p.

Is it possible to record in HBR mode in 25p? I could'n find the exact answer around.

Well, if it's no possible to shoot 1080 25 progressive , maybe I have to sell it... :(

Is there some hope for my case?

Thank you in advance.

5DtoRGB or External Recording 25p

kazuo — Mon, 01 Oct 2012 00:30:38 +0000

Hi everyone,

Thanks for all the response to my last question on external recording.
You have been great in helping me understand if it is viable to record 25p externally.

My research has since uncovered other methods, and subsequently other questions.

I've been thinking about HDMI output from the GH2, and conventional wisdom has it that the camera's output is good enough only for monitoring purposes. But there are some who argue that GH2's HDMI output is clean enough for recording, despite lingering red channel issues. Whichever way you compare it with MTS recording on SD cards, the images are invariably sharper and richer in detail.

Considering this, which method then produces better footage: hacked 25p MTS then transcoded via 5DtoRGB to ProRes 422, or external recording via HDMI to ProRes 422?

I am working in a 25p environment. Cheers

Is 25fps/1080p with hack and cranked bit rate (eg. 176mb/s) possible or not?

Bania — Sun, 26 Aug 2012 04:29:41 +0000

I've been scouring the net and honestly can't find a straight answer to this question. I've got a project starting on Wednesday that needs to be shot in 25p... My guess is that this still isn't possible, since I haven't stumbled across anything to the contrary. But I would absolutely love for someone to tell me I'm wrong.

GH2 1080 25P

alewelsh — Sun, 15 Jul 2012 18:10:43 +0000

Hi Everyone! I hacked my GH2 using stable settings and is working 100% fine!

Either way, today I can shoot at 1080 50 i / 1080 24p / 720 25p

Does anyone knows a hack that would allow me to shoot at 1080 25p?

Thanks in advance! Best regards,

Alejandro

Nikon D4 Video - Available Light, Internal Recording Codec

Aria — Mon, 19 Mar 2012 18:01:12 +0000

Here is a video that someone made using a Nikon D4 under available light. I don't see any mention of HDMI recording so it seems to be all internal codec. I actually like the look of it. It's a different look than the typical Canon look many are used to, but it still looks good to me for an internal codec.

GH2 adds missing AVCHD 29.97PsF… but worsens its already non-standard HDMI output

Icarus Patch - Just For HBR (current: 0.0.6 60mbps 25p stable, GOP6)

Athiril — Mon, 27 Feb 2012 05:12:17 +0000

LATEST: Icarus Alpha Test 0.0.6

Updated to GOP6 from GOP5, to fix stuttering.
up to 60mbps
2x trick mode in some scenes (Death chart)
QP16
Borrowed I, P, B frame scaling from Flowmotion
Improved Stability, so far have not been able to crash this in any test

Icarus 0.0.6 (indoor scene, f/2.8, 24mm, ISO3200, custom WB) (first couple seconds had rough motion, second half of bitrate distribution is what you normally see fairly static, where as movement scales up the B frames), typical B frames larger than Flowmotion's I frames.

Flowmotion 1.11 (same as above), much lower bitrate (imho it just cannot deliver with HBR modes), also crashes death charts with speed errors.

See what you think.

This is currently an Alpha Test. It needs more testing, but since I am pursuing the best HBR can offer, I've always found full daylight to be the bane of any attempt at raising HBR bitrate, I shall see how it performs in the morning in that regard.

Interlacing artifacts in new 25p mode

fatpig — Sun, 18 Dec 2011 07:37:13 +0000

Hi guys,

I had a shoot of a band yesterday, and i wanted to share this picture with you.
It does seem to have some interlacing artifacts at the top of the guitar.
what do you think?

First short, shot in 25p with leica 25mm 1.4 Poor Sleep Quality

klem007 — Sat, 14 Jan 2012 11:51:17 +0000

I did two years of animation but called it quits and started film this year. This is my first short i made, ever. Bought myself the gh2 and loving it ever since :) Anxiously waiting for the pal-land hack =)

All shot between 1.4 and 2.2

enjoy!

GH2 MJPEG 1080p 25 fps.

Athiril — Mon, 12 Dec 2011 07:00:37 +0000

Odd. Last time I tried the Change fps function for MJPEG it just fubar'ed all the time.

Now I went to stock settings (original GH2) for MJPEG with 25 fps, worked. So loaded the LPOWELL 100mbps/night 1080p settings, added 25 fps changed, works on my GH2. I'm not sure if it's merely dropping 5 frames out of every second (don't think it is). But if you shoot 1/25th, not sure if that it'd matter?

I'll try to examine it at some point with some linear motion at fixed speed, and look for 'jumps' in space.

My test file is reported as 75,697 kbps. Or 74 mbps. Which would be 88.7 mbps @ 30 fps, at the same average size/compression per frame. Available recording time is reported as 3m 12s. Recording on a Transcend 32gb class 10.

Test file was shot at ISO 2500, probably a stop underexposed still by the looks, just messing around in indoor light.

I'll do some slow panning on a monopod tomorrow with shutters @ and greater than 1/30th, and upload that.

Also I have gotten sizes a bit above 1080p working fine before too, which is useful I think for stabilising software if (such as deshaker) if you can shooter slightly wider than you want/need, so you don't have to blow up (or blow up as much) back to 1080p frame size for a 1080p output workflow. Combined with 25 fps would be great.

720/25p strange behaviour on GH2.

rogerpilly — Thu, 28 Jul 2011 05:31:48 +0000

I did a shot with 720/25p on a hacked GH2 with a 32 MB Bitrate (just for the record, I don't think the BR is relevant in this matter). Obviously I should have done more test... but this is the story:

The footage looks really good to my eyes and plays smoothly on camera and using VLC with the RAW footage. So, I tried to import it into FCP with conversion to Apple ProRes, as I usually do. Big surprise, at least to me that I don't understand how the coded technically works. The clips play at 50% speed, in a perfect and beautiful slomo! But it's not what I want! And also the second half of the clip does not get imported.

In other words, I see the entire clip in the preview window of the Log and Capture Tool (even though, if I try to play it, it doesn't play smoothly, it's all chopped, as if it had difficulty interpreting the TC) and the duration is correct. When imported, the duration of the clip is the same, but at 50% speed, so the clip ends after the first half.

Does anybody has an explanation? And, more important, does anybody know a work around to be able to use the footage? I would prefer at normal speed, but even in slomo it could be okay if I could capture the entire clip!
Thanks!

Wow - Panasonic ‘impressed’ with GH2 hack, vow to bring 25p update

Felix — Fri, 26 Aug 2011 16:06:36 +0000

In an interview with EPhotozine Panasonic talk X lenses (as first exclusively revealed by EOSHD last week) and the GH2.

Mr Uetmasu product developer:

A firmware update may be coming for the GH2 to add support for 25p, and additional improvements in video abilities. If there are features you want adding, contact Panasonic and let them know. They are aware of the work the “hackers” are doing and are impressed with their work, but that they (Panasonic) need to test everything / confirm there are no problems before rolling out updates. The GH3 is not due imminently, as the GH2 is still extremely popular, but that there is a high end GF series camera in the works.

Will be interesting to see what the ‘other’ video improvements are! Hopefully AF tracking and 60p.

Does this mean our (my) 25p prayers have been answered???
