Interlaced source video to what ??

Hello and please help. I know this question has been discussed over and over but I can't seem to find an answer. Many topics I have read are older and therefore don't take into account tvs/displays that we use today.

I have numerous home videos from a Panasonic SDR H200. It created SD videos and I have pasted the media info from one of the files below. I am combining many of these smaller clips for organization and want to save as MP4 (h.264) which will also save some space.

My question is the original video is interlaced. Everything that we will be watching these videos on are high definition tvs, monitors, etc. which are all progressive. I will not be burning DVDs but saving on external hard drives. What is my best option for output? Keep it interlaced or make it progressive? I've tried both ways and am struggling to see which is better so I'm wondering which should be better?? I can definitely see the "lines" in the interlaced version but the progressive version doesn't necessarily look better, just different.

And why is the size 704x480 rather than the standard 720x480? Just trying to learn.

Thank you!

Your mp4 need to be progressive. Only time you export to interlaced is for burning to a video disk.

The reason it does not look great on a HD tv is that the resolution of the mp4 is SD Standard Definition.

You are blowing the image up more then twice. Your tv does upcale the image.

And why is the size 704x480 rather than the standard 720x480?

dont know post screenshot of your export settings. Might be widescreen image in a 4;3 frame?

Thanks Ann. I did forget to post the info from mediainfo. I did figure the display would not look good on tv because it was blown up so much but I really can't say the interlaced or progressive version looks better over the other.

Thanks for helping me...I am well versed with photos but I'm trying to learn all this video stuff now.

How can a widescreen image be displayed in a 4:3 frame? Are parts of the image just cropped off? In which case it would be better to export as 4:3 to get the whole picture?? I'm guessing this might have something to do with the pixel aspect ratio but please clarify for me. I see aspect ratios as 4:3, 16:9 and as various decimal numbers 1.783, etc. and I know there are image ratios, pixel ratios and display ratios but don't know much beyond that at this point.

This video has some pretty unusual specs, rv. Some specs that can be potentially challenging.

That 704x480 pixel resolution was a real bear to work with. And it's not likely there's much you can do to make it look good on an HDTV.

I'm not sure what Ann will recommend, but I'd recommend you run the video through Handbrake to convert it to a more easily editable format. I can't promise this will fix the MOD/MPEG's file's unusual aspect ratio, but it's worth a try.

In Handbrake, set the Output settings to MP4. Under the Picture tab, set the Width to 720. Set Anarmophic to Custom and then type 480 in as the Width. (You may also need to set the PAR width to 1.02.)

Under the Video tab, set Video Codec to H,264 (H.264) and set Framerate to 30 fps and Constant Framerate.

These MOD files had numerous issues, but this should at least make the video file editable in Premiere Elements (assuming you have one of the most recent versions).
