Are there any difference between these two test films or?

Can I set Dolby level with both of them?

You can try but I wouldn't recommend using any Dolby produced analog test films at all until you can check their accuracy. The Dolby made films done over the last three or four years have been some of the more inconsistant test films produced. They are very off the mark some of the time and good at other times. If you don't have the capability to check them then you have no idea if your alignment is correct or not.

Test films that are accurate and on the money are available from NT Audio-Visual. I recently discarded almost all of my Dolby analog test film... some was good and some was bad... There's no time to fool around in this regard....

Hello Mark,

I found the following contact information for NT Audio Visual:

Is this the company you are refering to? If so, do they have a catalog or website where they list their products.

Thanks...ERIC

Yes that's real problem, because i think that mine 69T isn't good because during loop playing in projector i hear some pip's, and sound changing, on other way cat. 1012 playing ok, and i can set level with them, I'm gona try it on some system that is already aligned to see what level would be indicated.

Yes.. I don't know if they have a catalog but they probably do. Just call and ask to talk to Ada.

Marin,
How do you know the system you will check your film on was aligned with "good" film....... [Confused]

Reminder, as MArk pointed up....don't use any Dolby level test film, I have some of them (cat 69T) but they do have different levels. NT Audio makes great test films printed directly on B/W stock.

NT audiovisual is closed and Dolby ran out of test film long ago. 1012, is Dolby tone with and SR.D track. Original 69T had no SR.D track but this was added later if memory serves. Steve will be along to correct me if I'm wrong.

I have a small quantity but am running out. At some point someone will have to make something resembling the best ones Dolby made. Cat. No. 97, Cat. No 69T and Cat. No. 69P. The original and most accurate Cat. No. 69 was shot on Black and White stock and had both Pink and Tone tracks.

Posted by Steve Guttag (Member # 268) on 02-07-2016, 09:02 PM:

Oh...back in the day...Dolby was always all over the place on their tone/noise...particularly the pink noise. We would measure each new batch as it came in...this is particularly true on the color stock CAT69P. Sam is right that the black and white dual track was more uniform though there were bad batches.

Dolby had gone to color stock and separate tracks before SR*D was applied to them.

USL distributed their own dual track pink/tone. The USL pink was recorded at the same level as tone (50%).

The best was NTAV's stuff. That is what we ended up using for critical stuff. Very uniform from batch to batch. Their RP40 equivalent was the best too.

NT made all the Black and White Cat. No. 69 for Dolby. Don't remember about the color test film.

USL used NT for test films as well.
