What is the best way to encode 1080i 25FPS h264 to 720p? The stream is 17Mbps and would like to get that somewhere 5Mbps.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Use x264 encoder. Use it together with a gui like megui, hdconverttox, etc , use a high quality profile.
-
When I try to start encode it says NO VIDEO SEQUENCE HEADER FOUND, NO DATA CHECK YOUR PIDS? My original files are in .ts container.
-
Is there more helpful sites than this? Havent got answers any of my questions really.
-
You must provide more information like what SOFTWARE are you using? What is the video codec in the ts file?
And this is not any blu-ray ripping conversion. Moving you. -
Can you open the media file in MPC and does it play ?
Do you have haali media splitter and ffdshow installed ? -
ok create a script then
In notepad, write the following, save, change extension from .txt to .avs (change paths & filenames to match)
DirectShowSource("video.ts")
Load the .avs into megui, can you see the preview?
PS. megui might be more difficult to use if you are new to this, ripbot264 would be much easier -
What OS are you using? win7 ?
If so you need preferred filter tweaker to enable ffdshow
Do you have the correct paths and filenames?
DirectSHowSource("C:\...video.ts") -
answer ALL the questions above first , and did you try all the suggestions so far. Be specific
-
you have tried both coreavc and ffdshow with preferred filter tweaker and neither work for the script ? did you try the tsmuxer re-wrap first ?
-
Sorry, I don't know what's going on, but it sound like you have system conflict issues. Maybe try uninstalling ffdshow, then re-register coreavc and try again
You can try ffmpeg based converters e.g. mediacoder, format factory , but they often have issues with transport streams.
IF you cut a sample with tsmuxer (split & cut tab) and upload to a free hosting site (e.g. mediafire.com) someone can have a look to see if the stream itself is the problem (to rule out your system configuration being the problem)Last edited by poisondeathray; 1st Nov 2010 at 12:19.

Thanks for the help, maybe I will try that.
Tried program called h.264 encoder and it encoded it without a problem, but it doesn't have really many options.
Because the h264 stream is interlaced 1920x1080, yet 25fps, what progressive size should I resize it? -
You would normally deinterlace it first, then resize to 1280x720 if your goal was ~5Mb/s (5Mb/s is too low for 1920x1080)
If you don't deinterlace it first, you will get strange resize artifacts -
Yeah, something like 720p. Also HDcoverttox opened and encoded file without problems. Do you have some setting suggestions for it?
-
Not sure, I haven't used hdconverttox before
But you should deinterlace, then resize to 1280x720 , try to find those filters in the program -
Great program, hdconverttox. Used encode: 1280x720@25, interlaced deinterlace filter, x264 5Mbps 2pass extreme quality, audio copy. Got size to almost 1/4 and overall PQ actually seems better, without the interlace errors.
Thanks everybody for answers.
