From Wikipedia, regarding international visitors to Theresienstadt:
The visitors spent eight hours inside Theresienstadt, led on a predetermined path and only allowed to speak with Danish Jews and selected representatives, including Paul Eppstein. Driven in a limousine by an SS officer posing as his driver, Eppstein was forced to deliver an SS-written speech describing Theresienstadt as "a normal country town" of which he was "mayor", and give the visitors fabricated statistical data on the ghetto. He still had a black eye from a beating administered by Rahm, and attempted to warn Rossel that there was "no way out" for Theresienstadt prisoners. A soccer game and performance of the children's opera Brundibár were also staged for the guests. Rossel reported that conditions in the ghetto were favorable—even superior than for civilians in the Protectorate—and that no one was deported from Theresienstadt.
While the preparations for the Red Cross visit were underway, the SS had meanwhile ordered a prisoner, probably Jindřich Weil, to write a script for a propaganda film. It was directed by the German Jewish prisoner Kurt Gerron and the Czech filmmaker Karel Pečený under close SS supervision, and edited by Pečený's company, Aktualita. One scene was filmed on 20 January 1944, but most of the filming took place during eleven days between 16 August and 11 September 1944. The film, officially Theresienstadt. Ein Dokumentarfilm aus dem jüdischen Siedlungsgebiet ("Theresienstadt: A Documentary Film from the Jewish Settlement Area"), was dubbed Der Führer schenkt den Juden eine Stadt ("The Führer Gives a City to the Jews") by Jewish prisoners. Completed on 28 March 1945, the film was intended to discredit reports of the genocide of Jews reaching the Western Allies and neutral countries, but it was only screened four times and did not achieve its objective.
And on the family camp at Auschwitz (housing Jewish inmates from Theresienstadt):
The SS deported around 18,000 Jews to Auschwitz from the Theresienstadt ghetto in Terezin, Czechoslovakia, beginning on 8 September 1943 with a transport of 2,293 male and 2,713 female prisoners. Placed in sector BIIb as a "family camp", they were allowed to keep their belongings, wear their own clothes, and write letters to family; they did not have their hair shaved and were not subjected to selection. Correspondence between Adolf Eichmann's office and the International Red Cross suggests that the Germans set up the camp to cast doubt on reports, in time for a planned Red Cross visit to Auschwitz, that mass murder was taking place there. The women and girls were placed in odd-numbered barracks and the men and boys in even-numbered. An infirmary was set up in barracks 30 and 32, and barracks 31 became a school and kindergarten.

What is the Revisionist consensus on this question, if any? I would imagine it is possible to concede that a propaganda effort was underway that was at least somewhat deceptive (considering Allied nations were using their propaganda in the exact same way)—not to conceal mass murder nor 'gassing' but perhaps to at least avoid media exposure of the effects of the typhus epidemic, other disease and malnourishment which are generally acknowledged by all to have been present. Still, I am also inclined to believe there may be a better explanation, perhaps a refutation of the notion that these were 'propaganda ploys' at all, given Allied propaganda distorting the true operations of the NSDAP is a far more common than evidence of actual deception on the latter's part.
