1230868	2011-09-14 01:02:00	I want to render TS mpeg2 video files to mp4 1280x720 to play on my PVR but when I use MPEG Stream or Vegas Studio 9 the rendering takes about 13 times as long as the original video (i.e. a 1 hour show takes 13 hours). I have tried a number of video converters (Super, Prism, Free Converter etc) and although the results play back on DixX player they only play back the audio on the PVR. Any suggestions would be appreciated.	Krad (7878)

Some software reencodes which is very slow but gives good quality, others transcode which is much faster but can result in lower quality. Handbrake is a good free transcoder that might be worth a try. If you have a compatible graphics card there are some encoders that can use it to accelerate the encoding as well, but I'm not aware of free ones. Badaboom is supposed to be very good and has a trial version, but is mostly aimed at portable devices like tablets and smartphones with it's output options.	dugimodo (138)

Original source is TS m2t stream from upscaled to 1080i sd and hd broadcast via satellite from NZ channels and SBS. Using Ultraplus 9000 PVR. Copies of programmes are made via USB flash drive to computer and edited using MPEG Stream or Vegas. Experiments show that only 1280x720 mp4's will play back when transferred to the PVR. Quality is very good. AVI files not recognised. Some programmes I simply burn to DVD as mpeg1 files, no problem. Just would like to transfer personal videos to PVR. Would like a faster render if possible!	Krad (7878)

Will try Handbrake and check out the video cards. Cheers.	Krad (7878)

1230874	2011-09-16 02:48:00	You should try the XviD code with MP3 audio in an MP4 container. Handbrake will help. Handbrake says they do not use the Xvid code any more. I tried using Handbrake: mp4/720x576 (source)/mp3 dolby at 160/ and it played back on PVR but jerky. Any suggestions? Should I experiment with advanced settings (deinterlacing etc)?	Krad (7878)
1230875	2011-09-16 03:30:00	You could try googling handbrake settings for your model PVR, maybe someone out there has already been down this route. Otherwise I guess just experiment, the ipad preset actually works fairly well with a lot of things.	dugimodo (138)

1230877	2011-09-18 21:04:00	Me, I would use the freeware Mediainfo to find the parameters of a file that I know plays OK on the PVR. Then use the freeware Xmedia Recode to convert the source file to those parameters. When I use MPEG Streamclip the "natural" result is the ts container but I found it is better to go one step further and use that program to output the file in the mpg container. Takes only a minute or so for a 1 hour movie. For some unknown reason this speeds up subsequent conversion In Mediainfo I would particularly note the profile and level eg main@level4 or something. Also the video bitrate. And the framerate. I had trouble with wmv conversion going extremely slowly and the problem was the framerate. The converting software was set to "copy original framerate" but it was interpreting the source file as 1000fps! Still played OK but the quality was poor. Forcing the output framerate to 25 solved the problem.	BBCmicro (15761)
