BobbyG Posted February 19, 2019 Share Posted February 19, 2019 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. Link to comment Share on other sites More sharing options...
BobbyG Posted February 19, 2019 Author Share Posted February 19, 2019 Also, I'm running V5.02 of Video Pad and x264v7 is the codec. Link to comment Share on other sites More sharing options...
borate Posted February 19, 2019 Share Posted February 19, 2019 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. Link to comment Share on other sites More sharing options...
BobbyG Posted February 19, 2019 Author Share Posted February 19, 2019 I don't use projects. Link to comment Share on other sites More sharing options...
borate Posted February 19, 2019 Share Posted February 19, 2019 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. Link to comment Share on other sites More sharing options...
BobbyG Posted February 20, 2019 Author Share Posted February 20, 2019 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. Link to comment Share on other sites More sharing options...
borate Posted February 20, 2019 Share Posted February 20, 2019 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. Link to comment Share on other sites More sharing options...
BobbyG Posted February 20, 2019 Author Share Posted February 20, 2019 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. https://www.dropbox.com/s/geu26nrln8yirhk/testH264.zip?dl=0 Link to comment Share on other sites More sharing options...
borate Posted February 20, 2019 Share Posted February 20, 2019 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. Link to comment Share on other sites More sharing options...
BobbyG Posted February 20, 2019 Author Share Posted February 20, 2019 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 Posted February 21, 2019 Author Share Posted February 21, 2019 I already generated MPEG4s to try. They play just fine. Link to comment Share on other sites More sharing options...
borate Posted February 21, 2019 Share Posted February 21, 2019 Hints that the MED800X3D doesn't play nicely with VP's H264 encoder. But at least you have a workaround. Link to comment Share on other sites More sharing options...
BobbyG Posted February 21, 2019 Author Share Posted February 21, 2019 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.

borate Posted February 21, 2019 Share Posted February 21, 2019 Two H264 (mp4) encodings were tested. Link to comment Share on other sites More sharing options...
BobbyG Posted February 21, 2019 Author Share Posted February 21, 2019 Those play just fine. Is the codec being used to generate them x264enc7 11/10/2014 or a newer version? Link to comment Share on other sites More sharing options...
borate Posted February 21, 2019 Share Posted February 21, 2019 Precisely. 11/10/2014 1.52MB Link to comment Share on other sites More sharing options...
user007 Posted February 21, 2019 Share Posted February 21, 2019 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.

user007 Posted February 21, 2019 Share Posted February 21, 2019 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. Link to comment Share on other sites More sharing options...
