Blank screen during play on mulitmedia palyer

BobbyG

MP4s created using H264 encoding results in a blank screen during play on my MED800X3D multimedia player. MP4s from other editors and cameras (e.g., GoPro) play just fine. Output settings are 1280x720, 29.97 fps.

Also, I'm running V5.02 of Video Pad and x264v7 is the codec.

Let's see your project (not the export). Instructions - http://nch.invisionzone.com/topic/23659-tips-for-getting-help-on-this-forum/ Be sure to share it, then paste the link here.

I don't use projects.

Whatever is on the timeline - THAT'S the project. Follow the instructions above and someone will test it by exporting at your specified 1280x720, 29.97 fps, H264 settings.

Suggest also that you test export using the latest version of VP. Many improvements/fixes have been made since v5.x. Retain the install file of your current version.

BobbyG

OK, I'll do the "project" thing. I can't test export it using the latest version unless I buy it because exporting is not allowed in the demo version.

Some export formats may still be available for you in the trial version. But no need to export in order for someone to run your project.

Here's the link to my project files. I exported both mp4 and an avi H264 versions. The avi one plays correctly on my MED800X3D, the mp4 does not (blank scrren). Both play OK on my PC.

No play issue on the PC at the settings you specified. But, of course, it cannot be tested here on your standalone player. That said, using those same settings the video file was burned to a CD and looked fine on a 51" screen driven by a Blu-Ray standalone player.

Suggest that you instead output an H264, Mp4 at 60fps variable, 1920 x 1080 which most closely matches the source file. You might also export try 30fps constant or 60fps constant.

Report your results here.

BobbyG

Tried all 4 combinations. None play video on my player although audio plays. 60fps variable results in "unsupported format" on both my PC (using VLC) and my player. 30fps plays on my PC and results in "video unknown" on my player. I have lots of videos generated in 2017 and early 2018 with VideoPad using H264 encoding with various output settings that play on my player. Something changed after that.

BobbyG

I already generated MPEG4s to try. They play just fine.

Hints that the MED800X3D doesn't play nicely with VP's H264 encoder. But at least you have a workaround.

BobbyG

Well it played nicely with H264-encoded videos generated a year ago. What would be useful to me is for you to generate one with the latest version of VP since I can't. That way I could see if the latest VP H264 encoder "plays nicely" with the MED800X3D.

Two H264 (mp4) encodings were tested.

BobbyG

Those play just fine. Is the codec being used to generate them x264enc7 11/10/2014 or a newer version?

borate

Precisely. 11/10/2014 1.52MB

BobbyG,

Your original file has 1920x1080 59.94 fps, your avi file has format 1280x720 frame rate 29.97, however your mp4 file has format 1280x720 frame rate 30.30 (which is not standard frame rate). Just use correct video standards values like export format Youtube 1080p or 720p and 29.97 [TV NTSC] in case your player supports NTSC standard.

BobbyG

Nope. Doesn't work. I give up.

No idea then, BobbyG. My 10 years old (2008) Western Digital WD TV HD MEDIA PLAYER WDAVP00BE (PAL version) has no problems to play both these PAL and NTSC mp4 files.
