H264 Import screwed - MF6

Post by labtecy »

Hi

Ive recently been checking the various consumer level applications out so that i can try and author HD-DVD in H264 format. Unfortunately i havent seen any packages which can do this easily. However i was told that MF6 although wouldnt convert other formats to H264 on a HD-DVD, it would keep them in the existing format if the file was HD-DVD compliant.

Unfortunately when i import a H264 file into MF6, it goes all crazy and reports rediculous space requirements before it will let me burn it to disc/folders.

For instance

1. I took a WMV file that i converted from another application into a HD-DVD compliant file using H264 encoding, the file was a 30 second grab from a HD movie. The file on my desktop is 50MB, when i import it to MF6, it tells me i will need 60GB (yep GB) of space for the resultant disc (no menus or any other videos).

2. I demuxed a EVO file from a HDDVD (Departed trailer), i then place the H264 file into MF6 and again it reports about 50-80GB for the disc, even though the import is only 100MB and shouldnt need any trans/recoding as its HDDVD compliant.

Depending on how much compression the H264 is using usually a fast calculation would be about 4 times larger then the source H264 video.
You have to set this manually as your "Project Properties". No program can tell reading the h264 file what's it's previous hd-mpeg2 equal originally was encoded at.

On the average a 100MB h264 video converted to hd-mpeg2 would be approx 400MB.
Hd-Mpeg2 is approx 200MegaBytes per Minute @ 25000Mbs, you can drop this down to 18000kbs and it's still usually acceptable video.

Only guessing, sounds like your conversion programs to avchd format may not be converting properly. I don't know, MF6+ supports importing AVCHD from it's tested list of avchd consumer recorders.

If you can get a AVCHD file into the timeline of MF6 right click on it and select "Media Properties". Look at the properties & check the time in seconds of the video that MF6 is reading from the file. Most likely the time in seconds is wrong and MF uses that as it's calculation to create a mpeg2 from it.

No, maybe creating a AVCHD disk will be in the next release.
The do-not-convert compliant video files in MF refers to mpeg video, both standard & highdefintion.
