I'm using Pinnacle studio 22.2 ultimate. i was exporting a 1 hour project to MP4 H.264 format every 8 out of 10 times it shows export completed and exports a 0 byte file or an unplayable 1.63GB file with a vlc player logo without the video tumbnail. Sometimes it freezes in the middle of the export process. Sometimes it luckily exports playable H.264 file.

My pc spec :- Windows 10, AMD R5 1600, Zotac GT1030 2GB, Adata 2400MHz 8GB DDR4 RAM

Is there a temporary MP4 file in the same export location that has your correctly exported project?  It copies the temp file to the named file after exporting.  Sometimes if there is not enough room(Exported file size x 2), it can't copy the temp file to the named exported file.  You can close PS and rename the temp exported file to the filename you want.

Also, have you tried turning off Cuda support in Setttings?  Try setting it to NONE and see what happens.  I've seen in this forum that sometimes cuda produces an unplayable/corrupted file.

The unplayable VLC file, what is the extension?

When it freezes during export, is it at the same location?

What are your export settings?

You say MP4, what is the source of the file? What created it?

Also, exporting puts a lot of demand on your computer, how is the cooling?

That's a good point on the over clocking.  I've experienced that.  Turning it down 100mhz fixed it.

no temporary mp4 file is there in the export location, some times it produces 1.63 GB .MP4 file, no thumbnail (picture). sometime it freezes in different locations. my cuda support settings set to none by default. thanks for your reply.

i'm experiencing this problem with the MP4 Export format of H.264 Codec only MPEG4 codec is working fine eveytime. i think there is some problem with export with H.264 codec.

i am using .mts (1080p) files as source clips from SONY MC-2500 camcorder

Several things are weird here :

1.  Bit rate                    : 29.4 Gb/s   ????
2. Duration                    : 2 s 600 ms     ????

3. Width                       : 1 920 pixels

   Height                      : 1 080 pixels
   How a 1280 x 720 export setting can produce a 1920 x 1080 file ????
   

Are you using a built in preset setting for export, or are you using a custom setting?

Source file's bit rate is 22 Mbps. Tried Exporting with built-in 720p profile too (with H.264 codec), same result.

 here are some screenshots of source clip properties
