Infoseite // How do I cut Hi8 analog to video CD without quality loss?



Frage von samantha7:


I have analog Hi8 tapes, which would cut vodeo and archived on CD.
The tapes were recorded with Sony CCD-TR840E.
On loan I eineSony (Digital) DCR-TRV720E pal available.
Via Firewire port s.meinen of laptop I had the first tape with MGI Video Wave III (but only a maximum of 20 minutes) as a *. avi file with save about 4 GB.
This 20-minute file, I cut to about 12 minutes and on "Create" well with one compress a ca 500 MB *. Avi received file. This file I burnt on a trial basis with other periods of the HI6 band together on a video CD.
The reproduction quality was more than sobering lacked sharpness, colors are too pale, and strong jerk when panning, as if some pictures were missing, were striking deficits.
have looked at relatively, a copy of sequence Hi8 to VHC, which is known to be "no longer the original," but the quality of waste burned video CD is considerable.
What else could I change or cease to maintain a certain quality??

In a reaction, I'd be very happy.

Vorneweg - I think it is not worth the trouble, Selbstgedrehtes Hi8 or DV material to convert VideoCD. Even with a lot of try and optimize the image quality is modest. In SuperVideoCD it is my opinion only. Therefore, I recommend the DVD to enter directly into production, especially since the burners do not cost more for the blanks and the world.

So to all you problems ... 720x576 pictures of you go down to 352x288. And at the stream of 3.6 MB / s (DV) to 0.15 Mbytes / s (VideoCD). The fact that a loss s.Bildqualität naturally occurs, is not surprising.

Another source of poorer quality than is necessary, may be the additional AVI intermediate. In your case, you have therefore been about 80% of the image information thrown away (3.6 MBytes / s at 4 GB/20 min to 0.7 Mbytes / s at 500 MB/12 minutes) before the encoder drankommt for VideoCD. ..

Normally, one tries as few steps as possible reinzubringen compression in the process of source material on the target material. Maybe you can spend in your editing program directly to the edited video as a Video CD? If you absolutely must create a temporary file, it is favorably with the DV codec as a compressor.

The stuttering is very likely a false set of field order, either in the editing program, while exports in the mid-AVI or the encoder for VideoCD. The calculator needs to get communicated, with which field order walks in the recorded material. You can take a pragmatic approach and create a VideoCD with the other than it is now set field order. Extra careful when panning and zooming to see if it will no longer jerky.

The color-control you should make s.TV. In the Calculator, the colors are often different. It may be that the source material is there, colorful displays and / or that the target material is converted to the TV color areas / intensities. With some programs you can selectively disable the conversion to-and.

Good luck
The fat Stefan

Hello waldemar1100

If you have a DVD Burner, I agree with Stefan:
Quote: I recommend the DVD to enter directly into production

Otherwise, with CD burner would be the alternatives

SVCD or miniDVD

In the SVCD the data rate is higher (to 2600) than for VCD and the codec is MPEG2.
MiniDVD In this limit, however, there is no "correct" standard, so that many DVD players go on strike here.

So as a CD-Tip, I would have time to try the SVCD and DVD Burners otherwise buy (DVD Burner not cost the earth).

Hello Stefan,

Many thanks for your reply.

Tonight I read everything, and mostly understood.

Have synonymous detailed reply, but that is to find nitgends.

Therefore, this brief response as a test.
