Like Bouke said, more info. We have no idea what source video you are working with, what effects…and what computer hardware. Perhaps for an under-powered laptop such export times would be expected. But we have nothing to go on at this point.

The problem is Rolling Shutter, which most newer camcorders use. Meaning, rather than the entire image being grabbed from the sensor all at once, the image is being scanned top to bottom (over a brief period of time, like 1/30 or 1/60 of a second). Therefore, a strobe light might start to get recorded mid-frame!

With my old CCD-sensor video cameras, a photo flash would simply create a single bright frame. My newer camcorders (starting about 10 years ago), with CMOS sensor started doing what you have, showing half the photo flash on one frame and the other half on the next frame.

I don’t know of any post-fix unfortunately

I don’t believe this was a 24p source clip, or when I advance frame by frame I’d see a pattern of repeating frames and I don’t, there is movement on every frame. Seems it was a 1080i source (very) badly converted somehow.

A second issue you will need to correct – the supplied clip is 1920×1080 (Full HD), however the actual video portion is somewhat smaller with black surround, part way between 1080 HD and 720 HD at the odd size of about 1479×846 (720p is 1280×720).

Once you figure out problem #1, I’d probably export as 720p then. Put clip in 720p30 Sequence and scale until video just fits screen (about 88%), then export 720p30.

Good luck!

If using any .mp3 files in timeline, try replacing them with .wav as .mp3 can be an issue sometimes

Can you please be more specific in what you are needing to accomplish with this?

Why does it need to be that way and where is it going, to some special playback hardware? The more we know, the easier to form a good answer.

H.264 is typically delivered as an .mp4 file or sometimes in an .mov wrapper, but I’ve not seen it as an .avi and can’t think of why I’d need it that way but you must have a reason ????

Thanks

I looked up your recorder and seems like it can make a regular DVD video disc, which uses MPEG-2 for standard-definition video only, OR it can take the AVCHD high-definition contents of an SD card and put that onto the disc, though technically that is NOT a DVD, but rather is just” HD video clips on DVD media as data” and will NOT play in a standard DVD player (for computer use, perhaps Blu-ray player might work).

I’m going to assume you are running a cable from camera to recorder since you did say you do this in realtime. In that case, the recorder cares not what camera is used or what data rate is recorded inside the camera. What matters greatly is that the recorder needs an analog SD video signal to record to the DVD. Can the GH5 provide that? Plus audio. Basically, the Yellow, Red, and White RCA cables, can it output that? Maybe you have an adapter cable having mini plug for camera with RCA on other end?

Exporting to which drive? If external, formatting plays a role, for instance FAT32 has a 2GB file size limit.

If you can please post a screen shot of Export Settings perhaps we might see an issue there

Compression takes place in blocks of pixels, like 8 or 16 or 64. Numbers divisible by 8 basically. You can’t just dream up odd-number random dimensions and make it work, sorry, it breaks the encoder.

Hi Dan,

Unfortunately, the 2019 software seems to have a lot of bugs. I’d tell you to use 2018 but you would not be able to open the newer project in the older software. Switching platforms would likely not help.

Let me ask you this – what format are you exporting to, and what issues are you seeing? If trying to encode straight to H.264, what happens if you export to an intermediate codec first, such as DNxHD? Without knowing anything about the issue you are having, hard to make any suggestions. Please provide as much info as possible – using any third-party plugins? Does export always fail at the same point? Whatever info you can provide.

If you can provide a screen shot of Export Settings panel, that will also be very helpful

Thanks

Hi Phil,

Unlike physical media such as a tape or DVD, computers/devices are not tied to NTSC or PAL video limitations or specific frame rates – a digital file will work anywhere in the world – however the playback device must be capable of playing the format you are supplying and Ryan is correct that .mp4 is the de facto standard for wide compatibility with most any computer or device. Windows Media is unfortunately not going to be viewable for Mac, tablet, or phone customers.

I know what you mean about file size – many years ago, I did an instructional video (computer screen recordings) that ran about 3 hours. It was amazing how economical .wmv files were for that purpose! In my case, the viewer would always be on a PC since the training was PC-specific. That was before phones and tablets were in vogue for watching video and those screens are too small anyway for what I was showing.

With any codec you encoding too, the only way to make the file smaller is to lower the bitrate, as size= duration x bitrate, plain and simple. Try lowering the bit rate, perhaps increase the distance between keyframes. If you can perhaps share a screen shot of your export encoder settings for review, we can make suggestions on how to shrink the file size to something more palatable.

Thanks
